I read an article many years ago in a Mustang publication about the 68 S code mustang with a rare option...HIPO 390 with blacked out turn signal reliefs and rear taillight panel...I think it possibly was a dealer option?? It was basically a GT w/o all the bling. I think I may have one, that is why the article caught my eye. Has someone else heard the same? I've checked the registry and seems like everything is smallblock hipo. HELP!!
